Abstract

See full text

A toughened cyanoacrylate adhesive composition including a cyanoacrylate monomer and an elastomeric copolymer soluble in the monomer, the copolymer being the reaction product of an olefin C.sub.2-20 and a (meth)acrylate ester. The invention further discloses novel elastomeric copolymers which do not contain additives or functional groups which can interfere with the cure rate or stability of the adhesive composition in which they are included. Benefits of the copolymers include improved toughness of the cured adhesive composition as measured by Dynamic Mechanical Analysis.
